The submenus for genlock timing are: field timing, vertical offset, horizontal
offset, and fine horizontal offset.
Sets the amount of field offset using the left or right arrows. The maximum
amount of offset is two fields of advance or delay.
The Genlock Vertical Offset sets the amount of vertical offset using the left and
right arrows. The amount of offset can range from eight lines advance to eight
lines delay.
Genlock Horizontal Offset sets the amount of horizontal offset using the right or
left arrow keys. It will move in units of clock cycles so the exact amount will
vary depending upon the video standard selected. The total range of the
horizontal offset is
± ½
line.
Genlock Fine Horizontal sets the fine horizontal timing. These increments are in
sub-clock-cycle units. The total range of the fine horizontal offset is
± ½
line.
Black Signals
There are at least two analog black outputs available from the rear panel. (If the
SPG 422 is option 1, then there are six Analog Black outputs.) Configure each
separately for standard, timing, and signal type. If the selected standard is
different from the genlock input, the SPG 422 locks to the internal oscillator that
is clock-locked to the genlock input. The timing offset range is
±
2 fields and
±
8
½
lines.
Bars Signals
The Bars BNC connector outputs serial digital component color bars in either the
525 or 625 standard. A timing shift of
±
1 field and
±
8
½
lines is available. It is
not necessary that the Bars output and the genlock input be the same standard. If
they are not the same standard, then the signal locks to the internal oscillator that
is clock-locked to the genlock. Select all variables from the Bars signals menu.
Serial Black
The Serial Black signal is identical to the Serial Bars signal except the bars
signal information has been stripped off and replaced with black. It takes its
timing offset information directly from the Serial Bars signal.
